Core Viewpoint - The research team led by Professor Liang Changhai from Dalian University of Technology has achieved a significant technological breakthrough in the synthesis of high-end specialty monomers by successfully producing qualified 4-methyl-1-pentene (4M1P) with a purity of 99.3%, surpassing imported counterparts [1]. Group 1 - 4-methyl-1-pentene (4M1P) is a key monomer for synthesizing poly-4-methyl-1-pentene (PMP), which is essential for manufacturing ECMO membrane materials [3]. - ECMO (Extracorporeal Membrane Oxygenation) is a life support technology known as "artificial lung," regarded as a "lifesaving device" for critically ill patients [3].
